llllj lllll MACHINE FOR MAKING littlllilil'll'lll PRODUCT.

Application filed ileeember 15, 1919. florist No. 3%,966.

My invention relates to e roofing machine andrefers more particularly to e machine for impressing: elnhossu'lentsin sheet roofing which is afterwards cut into suitable roofing elements.

Among; its salient objects are to provide a machine for embossingroofing material which hits been saturated or coated with either nsphultic, bitinninous or like sul stances and may or may not have been granular surfaced; to provide nnischine that will produce enlhossinents either longitudinally ortransversely of the sheet so that convenient roofing elements may be formed by severing the sheet; to provide a ins-- chine for making embossed roofing shingles which are more ornamental when laid u pen the roof and have the appearance of tile or the like, and due to the embossed. giortions,

the shingles when laid are more res to the Weathering" and Warping eiii'er oi? the elements; to proi ide a machine which both einbosses the roofing and cuts it in a suitable manner for applying it to the root and in general to;prov1de a product and machine of the character referred In the drawing Fig. 1 is e diagrelnmatlc side GlGVEtlllOll of u roofing machine for producing transverse 30 bosses upon the roofing sheet.

Fig. 2 is a plan viewof the machine shown in Fig. 1. Fig. 3 is a detail View of e shingle unit produced in the machine shown in Fig. l.

a Fig. his a fragmentary detail View of a portion, of a roof laid with shingle shown in Fi n 3.

Reilzrring in detail to the drawings, the

- roofing sheet 1, Whichisof the usual type of saturated felt or bituminous coeted roe-- terial is fed by tiny. suitable means (not shown) through the embossing rolls 3 and t which are mounted upon suitable shoifts 5 and 6. A boss 7 running longitudinally of the roll 3 registers With n recess, 8 similarly arranged as the boss 7 on the roll 4. The

roofing sheet, after passing through. these rolls has elnbossments as that shown at 9 produced transversely across the roofing sheet! A slitter 10 mounted upon 3. suit able shaft 11 cuts the sheet longitudinally.

This slitter has a backing roll 12 which is the cutting edge of the slitter and has recesses let, which register with the embossments 9 to prevent mounted thereon and which d the einbossinents being ;tlettened by the led roll 12 in the slitting op tion. The rooting; sheet then passes throu the trei'isvers ting roll 15, which has the oi 111 175 bl coed onto the table 21 end dowi'i th chute 2. .2 to any suitable collector (not own}.

The shafts 5 and 11, which S'L'lppOl'l] the rolls 3 and slittcr it) are nioinlted in hearings similar to those supper up; the shell: J

hafts (l, end 1%) ere similarly ed in beeri (not shown). The is driven om ti o shaft 5 by sproclct end and the (:huin 2G.

tr 'tted to the bed rolls ii" and the pre :ure rolls l5 and 3 through the goers 2'? end 29, meshing with similar gzl'cnit's (not shown) on the l)G(.l roll shafts, 'lhe tii'rsme for supporting the beeriugs has been omitted for clcnrness. This frame may he oil u. 00111-- 111011 type employed in these rooting nun. chines.

In Fig. l is shown a moons of laying the roofing so that the embossed portion pro-- k? to the root lowing the l'lt't'll portions she tween the two einbossl'unei down close to the underl laying the roofing in this -r. the op pearzince Will he that ol a do root and. the troughs between the two einhossinents will be uniformly arranged nl'iovt. the en'lbossed portion of the underlying); shingle. producmg n very ornamentnl ellect.

llti ing an ornamental effect and at thesame time producing a roofing which 'is less susceptihle to the elements.

I claim as my invention:

In a roofing machine, the combination with means fer feeding a roofing sheet, of

,eircnlar embossing rolls having continuous parallel substantially angular aped bosses transversely of the periphery thereof for impressing einbossments'transversely in the roofing sheet, a rotating element having cutting means disposed longitudinally thereof for severing thesheet into suitable shingle elements, and means registering with the formed. ernhossments to preserve the shape thereei'i While the sheet is being severed.

2. In a roofing machine, the combination with means for feeding a roofing sheet, of

circular embossing rolls having continuous parallel substantially angular shaped bosses transversely of the periphery thereof for impressing embossments transversely'in the disposed longitudinally "and transversely thereof for severing the sheet into suitable" shingle elements, and means registering with the 'formedembossments to preserve the shape :thereof while the sheet is being Severed.

3.1-In a roofing machine, the-combination mg sheet, rolls having peripheral bosses for impressing continuous ridges h'aving s uare cornered configurations transversely o the sheet at predetermined intervals, and means for cutting the sheet lon itudinally and transversely into suitable shingle elements, and means registering with the formed embossments to preserve their shape While the sheet is being severed.
